The lamina of a leaf is the flat, expanded part of the leaf that is responsible for photosynthesis. It is made up of layers of cells that contain chloroplasts, which are the organelles that capture sunlight and convert it into energy for the plant. The lamina also helps to regulate the exchange of gases, such as carbon dioxide and oxygen, with the environment.

What is the structure and function of a lamina in a leaf?
The lamina, also known as the leaf blade, is the broad, flat part of a leaf. Its main function is to capture sunlight for photosynthesis, which is the process by which plants make their own food. The lamina is made up of cells that contain chloroplasts, where photosynthesis takes place. Additionally, the lamina helps to regulate the exchange of gases, such as carbon dioxide and oxygen, with the environment.
What is the function of the external leaf structure?
The external leaf structure serves to protect the internal tissues of the leaf, regulate gas exchange through tiny openings called stomata, and capture sunlight for photosynthesis through chlorophyll-containing cells.
What is the function of a stipule in relation to a leaf structure?
A stipule is a small, leaf-like structure found at the base of a leaf stalk. Its main function is to protect the leaf bud as it grows and to help regulate the flow of nutrients to the leaf.
What is lamina in a plant?
The lamina is the expanded portion or blade of a leaf and it is an above-ground organ specialized for photosynthesis. For this purpose, a leaf is typically, to a greater or lesser degree, flat and thin, to expose the chloroplast containing cells (chlorenchyma) to light over a broad area, and to allow light to penetrate fully into the tissues.
What is the structure that attaches epithelial cells to the basal lamina?
The structure that attaches epithelial cells to the basal lamina is called hemidesmosomes.

How does a pinnately compound leaf differ from palmately compound leaf?
In pinnate leaf the leaf lamina forms the leaflets whereas in palmate leaf the lamina becomes palm like.
What is the blade of the leaf?
It is lamina, the expanded part of the leaf.

What is the thin part of the leaf called?
The Blade, or lamina, is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells.
What is the structure that attaches epithelial cells to the basal lamina?
The structure that attaches epithelial cells to the basal lamina is called hemidesmosomes.
How do lamina in plants help photosynthesis?
Lamina, or the leaf blade, is the broad, flat part of a leaf that maximizes surface area for light absorption. Its structure contains chloroplasts, which are essential for photosynthesis, allowing the plant to convert sunlight into energy. The thinness of the lamina facilitates efficient gas exchange, enabling carbon dioxide to enter and oxygen to exit, further enhancing the photosynthetic process. Overall, the lamina plays a crucial role in optimizing the conditions for photosynthesis to occur effectively.
